btw, every time i consider closing my CSP for a better earnings card (like the Barclay Arrival for example), I see things like this:
You think British Airways Avios are worthless because of their fuel surcharges, but on destinations where they don't charge fuel surcharges, they're a steal! Can fly roundtrip to Rio for just 15,000 UR points (which is practically nothing) and $450.
This is where the CSP shines. If you like to travel, don't close it. If you don't like to travel, then get a different card, because the CSP is a travel card.
